Chapter Summaries

Houtarou Oreki observed that the High School of Advanced Education was an unusual student-run academy and met his Class A classmate Sakayanagi Arisu. After a system notification called her a Tyrannosaurus, he was left wondering what the message meant.

• Oreki guessed that Sakayanagi was highly intelligent and could help Class A handle future problems.
• Oreki's system displayed the message that Sakayanagi Arisu was a Tyrannosaurus three times.

Houtarou Oreki received a superpower system that offered him a choice between taking Sakayanagi Arisu’s cane and investigating the school for 200,000 points. He rejected the task targeting Sakayanagi and accepted the investigation, which would earn him teleportation if completed.

• During the Gymnasium ceremony, Oreki activated a system that offered two tasks and threatened to send his older sister home if he failed.
• Teacher Mashima told Class 1-A that students had to live in the dormitories and explained their monthly Private Points.

• Oreki decided he could not take Sakayanagi Arisu’s cane and chose to investigate the school and earn 200,000 points.

Oreki learned that he could teleport home once he obtained the ability by completing his quest, so he investigated how to uncover the school's secrets efficiently. Class A pooled points to learn the truth, and Teacher Mashima revealed the school's class-based system and the uncertainty of students' futures.

• Oreki received a quest to investigate the school and earn 200,000 points, along with a reward that would let him teleport home once a day after gaining the ability.

• Sakayanagi Arisu suggested pooling points, and all forty Class A students agreed to contribute 50,000 points each.
• After receiving two million points, Mashima explained that only Class 3-A graduates received the advertised opportunities, and that monthly Private Points were based on Class Evaluation Points.

After learning how the school’s class rankings, behavior assessments, and Points worked, Oreki discovered his investigation mission was complete but still needed to earn 200,000 Points.

• Oreki questioned Kamuro after noticing she had continued following him after Sakayanagi left.
• Kamuro asked Oreki for a copy of the recorded school rules so she could share in the profits from selling them.

• Oreki and Kamuro went to the first-year area, where Kamuro asked which class he planned to sell the rules to.

Houtarou Oreki and Masumi Kamuro visited Class 1-D to sell information, where Oreki saw the class’s crude behavior and noticed Airi Sakura being humiliated by Yamauchi. Yosuke Hirata gathered the students, and Oreki identified the aloof Horikita as the beautiful girl who had drawn the Student Council President’s attention.

• Oreki ruled out selling information to Classes B and C because he would not harm Class A, so he and Kamuro went to Class 1-D.
• They overheard the boys ranking girls by their bodies, while a beautiful black-haired girl quietly read by the window.
• Yamauchi bragged that Airi Sakura had confessed to him and insulted her, while Sakura stood at the back door and heard him.
• Oreki knocked to reveal Sakura, then told the class he was selling information and warned that their discussion had cost them seven million in living expenses.
• Yosuke Hirata organized the Class 1-D students, and Oreki learned that the girl by the window was Horikita.

Houtarou Oreki offered Class D information about the school and the seven million Points they might lose, charging 10,000 Points per listener. When most students left rather than pay, Horikita Suzune volunteered to cover the shortfall, leaving her reason for being in Class D exposed.

• Oreki introduced himself and Masumi Kamuro as Class A students selling school information at a discount, including details about Class D's possible seven-million-Point loss.
• Kikyo Kushida and the returning girls learned that the boys' earlier discussion could cost their class Points, and several girls condemned the boys involved.
• Kōenji rejected the offer and left, then Yamauchi followed him, prompting more students to leave rather than spend their Points.
• Oreki set a minimum of 200,000 Points for the transaction, but only eleven Class D students remained.
• Horikita Suzune offered to contribute the missing 90,000 Points, while Kushida offered 10,000 Points before Horikita said she wanted to learn the school's rules.

Oreki explained Class D’s ranking and school rules, collected payment for his information, and completed his quest, earning teleportation powers. As he left Class D with Masumi Kamuro, they encountered Karuizawa and another girl arriving late.

• Oreki told Horikita Suzune that Class D likely contained students whose serious flaws outweighed their strengths, and explained how the school’s class rankings could change.
• Oreki collected Points from the eleven students who had bought his information, and they understood how Yamauchi’s group’s behavior could have cost the class seven million Private Points.

• Oreki told Horikita Suzune that the school likely provided free necessities and meals for students who ran out of Points.
• Oreki left Class D with Masumi Kamuro, and they met Karuizawa and a black-haired girl hurrying up the stairs.

After Kei Karuizawa hugged Oreki and thanked him for saving her, he wondered whether they shared memories he could not recall. He arranged for Masumi Kamuro to investigate camera-free spots at school so he could secretly use his new teleportation ability, then headed to his dorm room to test it.

• Kei Karuizawa recognized Oreki, hugged him, and messaged him that she was grateful he had saved her in the past.
• Oreki found no memory of meeting Kei Karuizawa and considered that a supernatural phenomenon might explain the missing memories.
• Oreki warned Masumi Kamuro not to underestimate Class D and pointed out that its disciplined students and capable social leaders could make it a threat to Class A.

• Oreki received Teleportation, which let him travel to places he had visited up to three times daily, and an additional reward that let him return home without limit.
• Oreki went to his dorm room, Room 303, to test his new ability.

Oreki used teleportation to return home after entering his assigned dorm room, while Teacher Majima reported Class 1-A’s early purchase of the school rules to the Chairman. The school awarded Class 1-A two hundred additional class evaluation points, and Hoshinomiya Chie complained to Sae Chabashira that Class B was being overlooked.

• Oreki teleported from his dorm room to his home and spent the afternoon relaxing.
• Teacher Majima told the Chairman and the other homeroom teachers that Class 1-A had pooled two million Points to buy the school rules.

• After the meeting, Hoshinomiya Chie complained to Sae Chabashira that the Chairman’s praise for Class A had ignored the promising students in Class B.

Chabashira concluded that Class D had squandered a rare chance to learn the exam rules, while Oreki rested at home with his cat before teleporting back to school. After Masumi Kamuro sent him a report on campus blind spots, Oreki decided to reward her with Points.

• Hoshinomiya Chie pointed out that Class D had learned the exam rules from Oreki, but Chabashira said she had little hope for her students after only eleven had paid to hear them.
• Oreki slept through the afternoon at home with his cat, Hayate, and noticed that the school blocked outside networks and phone calls.
• Oreki planned to use his Points to buy daily necessities at the school Shopping District, then teleported back to his dorm room.
• Masumi Kamuro sent Oreki a list of five places on campus without surveillance cameras.
• Oreki opened the transfer page and chose to send Masumi Kamuro 50,000 Points.

Oreki overheard Manabu Horikita scolding his sister Suzune and realized his earlier lie had led her to believe she was a seeded candidate in Class D. A quest appeared requiring him to choose between helping Class D reach Class A or earning 20 million points in three months, and Oreki chose the points mission.

• Oreki went to the Shopping District, bought supplies, and headed toward a camera-free vending machine to use Teleportation.
• Oreki saw Manabu Horikita confronting Horikita Suzune and listened as she defended her placement in Class D as the school's arrangement.
• Manabu told Suzune that Class D had almost never advanced and mocked her hopes, while Oreki realized she had believed his claim that she was a seeded candidate.
• Oreki considered the possibility that someone could use 20 million points to transfer him into Class D, then received a quest offering that outcome as one mission option.
• Oreki chose the second mission: earn 20 million points within three months for a supernatural physique, rather than join Class D.

Oreki photographed Manabu Horikita and Horikita Suzune in a compromising-looking moment, then used the pictures to make Manabu pay him 1 million Points. Manabu warned Suzune to learn how to handle deals and Points, then tried to punch Oreki, who had already moved out of reach.

• Oreki took eighteen photos of Manabu Horikita and Horikita Suzune, then evaded Manabu’s attempt to catch him.
• Manabu offered to buy the photos, and Oreki returned to the vending machines as Horikita Suzune recognized him.
• Horikita Suzune explained that she had paid Oreki 90,000 Points to learn the school rules, leaving her account empty.
• Manabu examined Oreki’s phone and found that the photo had been shared and downloaded, so he paid Oreki 1 million Points to settle the matter.
• Manabu told Horikita Suzune to learn how to make deals and understand the importance of Points, then tried to punch Oreki, who moved ten meters away.

After Oreki used Teleportation to evade Manabu Horikita’s attack, Manabu offered him points to help guide Suzune and keep her at school. Oreki considered refusing, but Manabu’s offer of a million points plus a monthly payment made the arrangement tempting as Oreki pursued his twenty-million-point mission.

• Oreki avoided Manabu’s punch by teleporting away, astonishing Suzune and leading Manabu to suspect his physical abilities were extraordinary.
• Manabu introduced himself as Suzune’s older brother and implied he had paid Oreki a million points to keep the exposed photos private and gain his help with Suzune.
• Oreki reasoned that Manabu wanted Suzune to remain at school and find a first-year student to guide her, but initially refused because he disliked troublesome work.
• Manabu offered Oreki one hundred thousand points each month to bring Suzune along and broaden her horizons, explaining that graduating students could exchange points for cash.
• Suzune’s surprise at the value of points revealed she had spent one hundred thousand on Oreki without realizing it represented real money, further worrying Manabu about her leaving school.
• Oreki checked his mission progress and saw that Manabu’s million-point transfer and promised monthly payments could help him reach his twenty-million-point goal.

Oreki negotiated with Manabu Horikita for advance Points and a Student Council secretary position, while Manabu arranged for Horikita Suzune to receive money. After the brothers parted, Oreki recognized Manabu was trying to tempt him toward the Student Council presidency, and Suzune headed to the Shopping District to buy necessities.

• Oreki asked Manabu Horikita to advance the Points owed for looking after Horikita Suzune, and they agreed on an initial 500,000 Points transfer followed by monthly payments.
• Manabu agreed to send half of the later monthly payment to Horikita Suzune and offered Oreki the Student Council secretary position, while barring first-year membership applications during his term.
• Oreki noticed Manabu's account held 45 million Points and suspected Class 3-A had pooled its funds for him to manage.
• Oreki inferred that Manabu was using the secretary position to tempt him to pursue the Student Council presidency.
• Manabu transferred Horikita Suzune 100,000 Points, and she told Oreki to take her along when he did things before heading to the Shopping District for necessities.

Oreki told Katsuragi’s faction that he had obtained a Student Council secretary position for one million points, and Katsuragi asked him to reserve it. As Oreki considered how Katsuragi would raise the money, his own quest to gather twenty million points remained far from complete.

• After homeroom, Oreki joined the group chat Katsuragi had made for twenty-two Class A students and learned Sakayanagi was not a member.
• Oreki announced that he had secured a Student Council secretary position for one million points, due by the first of next month, and explained that first-years could not otherwise join during Manabu Horikita’s term.
• Sakayanagi privately messaged Oreki asking whether he was short on money, making him suspect someone in Katsuragi’s chat was passing along information.
• During lunch, Oreki received Katsuragi’s request to reserve the secretary position while Katsuragi gathered the required points.
• Oreki checked his quest and saw that he had accumulated 1,693,500 of the twenty million points he needed within three months.

Oreki confronted Airi Sakura after noticing her following him, and learned she had come to thank him for intervening when Class D boys mocked her. He then noticed Kamuro watching them and went to join Sakayanagi, intending to discuss her message about his finances.

• Oreki spotted Airi Sakura following him to the cafeteria and asked what she wanted.
• Sakura said she disliked stalkers, then thanked Oreki for stopping Yamauchi from spreading rumors and for helping the class learn the school rules.
• Oreki realized the boys had apologized to Sakura after learning their ranking scheme could cost the class more than fifty evaluation points.
• Oreki parted ways with Sakura and noticed Kamuro watching them from nearby.
• Oreki collected his food and went to Sakayanagi's booth, planning to discuss her message asking whether he was short on money.

Oreki discussed Kamuro’s loyalty to Sakayanagi and advised her not to pursue Katsuragi’s Student Council position, then explained his plan to gather twenty million points as protection and potentially transfer someone between classes. Sakayanagi considered the idea of buying a student into Class D and concluded it would be terrifying.

• Kamuro quietly yielded her seat to Oreki and continued eating while Sakayanagi spoke with him.
• Oreki questioned Sakayanagi about Kamuro’s weakness and warned that Katsuragi’s Student Council bid could cost his supporters points.
• Oreki received 80,000 points, bringing his balance to 1,771,400, and Kamuro reacted with surprise at his increased funds.
• Oreki proposed gathering twenty million points to prevent expulsion or transfer someone to another class, and Sakayanagi considered the possibility.
• Sakayanagi said that buying someone into Class D would be terrifying, even though the classes could rise or fall in rank.

Oreki returned part of Kei Karuizawa’s points and discussed ways to use 20 million points with Sakayanagi Arisu. He then sought out Horikita Suzune to begin Manabu Horikita’s plan to improve her, learning that Class D had already lost 20 points.

• Oreki learned that Kei Karuizawa had transferred him 80,000 points and returned 30,000 to her, planning to repay the rest another way.
• Oreki proposed using 20 million points to buy a student or transfer into the graduating Class 3-A, and Sakayanagi Arisu said she would investigate whether either idea was possible.
• Oreki used his phone’s GPS to find Horikita Suzune in the cafeteria and told her he would begin after school to fulfill her brother’s request.
• Horikita told Oreki that Class D had lost 20 points that day because students ignored the rules and misbehaved during lessons.

Oreki urged Horikita Suzune to aim for twenty million points so she could transfer classes and earn her brother’s acknowledgment. As Horikita came to discuss how to obtain points, Sakayanagi sent Kamuro to follow Oreki, and Horikita concluded that there were few ways for students to earn extra points.

• Oreki told Horikita Suzune that collecting twenty million points could let her transfer classes and prove herself to her brother.
• Sakayanagi Arisu asked Masumi Kamuro to follow Oreki because she wanted to see how he would pursue twenty million points.
• After classes ended, Kamuro secretly photographed Horikita Suzune when she came to Oreki’s classroom.
• Oreki left with Horikita, who explained that she had researched the school’s point system and found few ways to earn extra points.
